PROBLEM TO BE SOLVED: To provide an exhaust gas facility capable of periodically removing fly ash of an inner wall provided at a position of facing the exit of a fusion furnace, and capable of suppressing accumulation of the fly ash.SOLUTION: An exhaust gas facility 2 is connected to a fusion furnace 1 for fusing an object to be processed, and from an exit 1c of the fusion furnace 1 introduces exhaust gas with fly ash containing molten salts and guides the exhaust gas to a post stage. The exhaust gas facility can periodically remove the fly ash containing molten salts, which adheres to an inner wall 2e provided at a position of facing the exit 1c of the fusion furnace 1, by gas jetted by gas jetting means 4, and suppresses accumulation of the fly ash. |
